AUTOMATIC PACKING-MACWFE.

To all whom it may concern:

Be it known that 1, CHARLES F. SMITH, a citizen of the United States,and residing at Dexter, county of Jefierson, State of New York, haveinvented certain new and useful Improvements in AutomaticPacking-Machines, of which the following is 'a specifica- My inventionrelates to automatic packing machines and has for its general-object theprovision of a machine which will automatically pack small boxes withsuitable material in the form of chips. These chips may be chewing-gum,candy, compressed tobacco, soap, etc.-

in its general construction, the machine of my invention includes arotatable assembling dial, with a box-feeding mechanism atone side and acover feeding mechanism at the other. To one side of the dial,substantially midway between the two feeding mechanisms, is arranged amaterial-feeding mechanism. In the preferred form of my invention thebox and cover-feeding mechanisms include a pair of oppositely-rotatabledisks.

I These disks are mounted concentrically and areso arranged that theboxes or covers are thrown centrifugally from the inner to the box.

I outer disks, from which they are delivered to the assembling dial. Theempty boxes on the dial are packed with the requisite quantity ofmaterial and the covers are auto.-

matically placed upon the packed boxes. In

its preferred embodiment, my new and improved packing machine includesan automatic banding the, dial opposlte thematerial-feeding mechanism.When a sealed box is discharged from the dial it is automatically fedinto the bandin mechanism where a band of palper le material isautomaticallfapp ied to the bottom and the sides of the sealed Ofcourse, if desired, the banding mechanism. may 'be omitted and thesealed boxes delivered from the dial to a suitable conveyer belt. Overthe assembling dial operates a plunger mechanism which insures theproper position of the empty boxes on the dial, insures the feeding ofthe material into the empty box, forces the covers onto thepacked-boxes, and discharges the sealed boxes from the dial. In thespecific construction shown in the drawings, the various operating partsderive their motion from a Specification of Letters Patent.

main drivin shaft journaled in the lower port on of t e machine bed, andthese connections are such as to'harmonize the movements of theoperating parts. I

-My invention also includes the provision of means for automaticallyfeeding suitable blanks or patches into the bDXEHEE blank being fed intothe box before the material is deposited therein, and the other blankbeing fed on top of the material in the box.

These blanks or patches may be of suitable material to act as aprotection for the con tents of the box; or, the top blank may be Wheresuch blanks are not desired, the blank feeding mechanisms may be omittedor disconnected from the operating shaft.

The various parts which go to make up the difl erent mechanisms of mymachine are mounted on a suitable framework or machine bed indicated asa whole hy hf. As seen from Fig. l, the general contour of thisframework is rectangular with rounded ends. Centrally arranged over thetop plate l of the machine loed M is the assembling dial To one side ofthis dial is the hon-feeding mechanism and to the other side thecover-feeding mechanism. The function of the assembling dial is toreceive the empty boxes and carrythem from the point at naeaeae whichthe box-feeding mechanism delivers tions which it includes will beconsidered separately under difi'erent headings.

Assembling dial and connectiona-The assembling dial D is a heavymetallic disk provided with a series of openings or pockets 2 adapted toreceive the boxes for packing. These openings arespaced apart at equaldistances around the periphery of the dial. In the particular design ofmachine shown in the drawings, the dial is provided with ten openings.Underneath.

- the openings of the dial is arranged a pair of arc-shaped plates 03and (P, as indicated in dotted lines in Figs. 1 and 9, for supportingthe boxes in the openings 2. These supporting plates are carried on thetop of suitable brackets (i and (i respectively, as shown in Figs. 19,21 and 22. The brackets 03 and d which follow the curvature of theplates at and 0 are rigidly mounted on the to plate 1 of the machinebed. At one end, t e box-supporting plates al and d and their brackets,are separated by the space d while at the other end they are separatedby the space at. As will be explained later on, the space 01 is providedfor the discharge-of the sealed boxes, while the space at isior thepurpose of accommodating certain parts of the material-feedingmechanism, to be subsequently referred to in detail. The dial has formedthereon a downwardly-extending bushing or hub 3 adapted to rest on thetop 1 of the machine bed. The hub 3 has an opening 4: into which extendsthe upper portion. of the sleeve 5. The dial D is rigidly connected withthe sleeve 5 in any suitable manner as by a key or spline 6.- The sleeve5 extends through the guide bushing 7 depending from the top plate ofthe machine bed. To the lower end of the sleeve 5 is secured thestar-wheel 8 by means of the key 8', or

otherwise. It will be seen that I the dial and the connected partsmentioned are rotatably supported by means of the hub 3 resting on thetop of the machine bed. The form of the star-wheel 8 is best shown inFig. 5. As seen from this figure, the starwheel is provided with aseries of radial grooves or channels 9 formed by outstanding ridges orshoulders 10. There are ten of these grooves shown, to correspond withthe openings 2 in the dial. Between the grooves 9 are providedperipheral recesses 11, which, as will presently appear, cause lockingof the star-wheel during its intervals of rest. A crank-arm 12 isassociated with the star-wheel for intermittently operating the same.The crank-arm is fixed to the lower end of a vertical counter-shaft 13,as best shown in Fig.= l, and carries at its free end a roller 1%arranged to enter the grooves 9 of the star-wheel for establishingoperative connection between the two parts. The counter-shatt- 13 ismounted in the bushing 15 depending from the top 1 of the machine bed,and is adapted to be continuously rotated through connections to bepresently described. How the continuous rotation of the crank-arm 12 isintermittently imparted to. the vstar-wheel 8 is perhaps bestillustrated in Fig. 24:, to which reference will now be had. lit will beobservedthat the hub of the crank-arm extends downwardly at 16 intohorizontal alinement with the star-wheel. This exten sion is rounded toform a locking surfacev 17 adapted to extend into the recesses 11 duringthe time that the roller 14 is out of engagement with the grooves 9 ofthe stanwheel. It will be clear from Fig. 24 that as long as the lockingextension 16 projects into one of the recesses 11, the star-wheel ispositively locked against rotation. The curvature of the cylindricallocking surface 17 of the extension 16 corresponds with the tilcurvature ofthe recess 11, so that the crankarm may rotate freely at alltimes. The direction of rotation of the crank-arm is indicated by thearrow a in Fig. 2%. V hen the arm reaches the position indicated indotted lines at 12 the roller 14 comes into operative engagement withone of the grooves on the star-wheel, and rotation of the latter begins.During the time that the crank-armmoves from the position indicated' at12 to the position indicated in dotted lines at 152", the star-wheel isrotated one-tenth of a revolution. The extension 16 is cut away at 18,so as not to interfere with the rotation of the star-wheel. During the11d interval that the crank-arm rotates from position 12 to position12*, there is no movement of the stanwheel. Furthermore, during thisinterval oi rest, the star-wheel is held locked against accidentalrotation, as 1th previously explained. As the assembling dial l) isrigidly connected withthe starwheel, these two members always move inunison. lit will be observed that T have provided a very simple andeiiicient means for 1241 producing intermittent rotation of theassembling dial by means of a continuously rotatable crank-arm whichperforms the additional function of locking the dial against movementduring its intervals of rest.

To the upper end of the counter-shaft 13 is fixed a gear 19 which is inmesh with the gear 20 fixed upon the upper end of the rotatable shaft20", as shown in Figs. 3 and 5. The gear 20 is in mesh with the gear 13c
